for the amateur artists of American Fork who are inspired to fill its sides.The story behind what has become known as the “Chalkbus” even inspired a mini documentary by college students,the DailyHerald reports.The idea to make it a rolling chalkboard came to Sherman when the bus was due for a new paint job and he painted it black matte primer and then gazed over at his daughter drawing chalk on the sidewalk.He invited her to try on the van,and the plan was formed.“People were like,‘Oh,you shouldn’t do that,peopl e are going to draw all kinds of horrible things on there,’ you know,‘You’re asking for trouble,’” Sherman said.“People really haven’t drawn anything bad there,they always draw cool things.”He started driving it several years ago,and frequently found drawings when he parked it in at the movie theater or grocery store.When he found someone drawing on the bus,he left them alone to finish before talking with them.“It’s always a positiveconversation,” he said.Sherman,a licensed marriage and family therapist,said the bus seemed to provide something people were missing.He took it each year to the Out of Darkness Suicide Prevention Walk in Salt Lake City and let people draw on it there.“A lot of people are really disconnected in society.And a lot of people suffe r in silence,”he said.“Anywhere I can find a little small connection,I think it just

you with many other health problems behind the scenes.2 However,for the same reason,music can be very beneficial if one is in pain.By distracting(分心) the mind from thepain,music,people say,can lower stress and anxiety levels.This,of course,can lead to less pain.Many people enjoy relaxing music in the evening prior to going to bed. 3 While the validity of the idea is still being assessed,the lowered stress can even be tied back to blood pressure.Similarly,according to researchers,listening to just 30 minutes of soft music every day may help with healthy blood sugar levels,through the lowering of stress and anes to heart health,there is speculation(推测) that it’s not the style of music,but rather the tempo that makes it so good for your heart health.In one European

As I was likely to be home rather late, I advised him to go into the kitchen and help himself to food and drink.Two hours later my friend telephoned me from the flat. At the moment, he said, he was listening to some of my records after having just had a truly wonderful meal. Now, he said, he was drinking a glass of orange juice and he hoped I would join him. When I asked him if he had reached the flat without difficulty, he answered that he had not been able to find the key under the doormat, but fortunately the living-room window just by the apple tree had been left open and he had climbed in. I listened to all this in astonishment. There is no apple tree in front of my living-room, but there is one in front of my neighbour’s!3. Listening ComprehensionA. True (T) or False (F)?For false statements, write the facts.1. There was a lot of noise in the Reference Library.FIt was silent in the library.2. The assistant did not take much notice of Philip when he came in.T3. Philip knew the Reference Library well.FPhilip had not been to this part of the library before.4. Philip was not interested in photography.FPhotography was one of his hobbies.5. The assistant nearly forgot to ask Philip how old he was.TB. Complete each sentence with relevant information from the passage.1. Most of the books on the shelves, such as dictionaries in many languages and encyclopaedias did not interest Philip.2. Philip would not have disturbed the readers if he had not dropped a book on the floor.3. The book that fell off his hand to the floor was not damaged.4. The assistant librarian told Philip severely to be more careful when he was handling the books.5. Philip did not know that he was too young to use the Reference Library because he didn’t see the notice on the door. Script:A Kindly Library AssistantThe silence of the Reference Library was broken only by an occasional cough and now and then by the scarcely audible sound of pages being turned over. There were about twenty people in the room, most of them with their heads bent over their books. The assistant librarian who was in charge of the room sat at a desk in one corner. She glanced at Philip as he came in, then went on with her work.Philip had not been to this part of the library before. He walked around the room almost on tiptoe, afraid of disturbing the industrious readers with his heavy shoes. The shelves were filled with thick volumes: dictionaries in many languages, encyclopedias, atlases, biographies and other works of reference. He found nothing that was likely to interest him, until he came to a small section on photography, which was one of his hobbies. The books in this section were on a high shelf out of his reach, so he had to fetch a small ladder in order to get one down. Unfortunately, as he was climbing down the ladder, the book he had chosen slipped from his grasp and fell to the floor with a loud crash. Twenty pairs of eyes looked up at him simultaneously, annoyed by this unaccustomed disturbance. Philip felt himself go red as he picked up his book, which did not seem to have been damaged by its fall.He had just sat down when he found the young lady assistant standing alongside him. “You must be more careful when you are handling these books,” she said severely. Satisfied that she h ad done her duty, she turned to go back to her desk. Then a sudden thought struck her. “By the way, how old are you?” she asked Philip. “Thirteen,” he told her. “You’re not allowed in here if you’re under the age of fourteen, you know,” the assistant said.“Didn’t you see the notice on the door?” Philip shook his head. He expected the assistant to ask him to leave. Instead, in a more kindly tone, she said, “Well, never mind. But make sure that you don’t disturb the other readers again, otherwise I shall hav e to ask you to leave.”4. TranslationA. Translate the following sentences from Chinese into English.1. 很清楚，在粗鲁的顾客⾯前，⼀些售货员感到很难保持礼貌待客。

高中物理选择性必修第三册课后习题第四章原子结构和波粒二象性 5.粒子的波动性和量子力学的建立

5.粒子的波动性和量子力学的建立课后篇素养形成必备知识基础练1.关于德布罗意波,下列说法正确的是( )A.所有物体不论其是否运动,都有对应的德布罗意波B.任何一个运动着的物体都有一种波和它对应,这就是德布罗意波C.运动着的电场、磁场没有相对应的德布罗意波D.只有运动着的微观粒子才有德布罗意波,对于宏观物体,不论其是否运动,都没有相对应的德布罗意波,都有一种波与它对应,即物质波,物质有两类:实物和场,所以B正确。

2.1927年戴维森和汤姆孙完成了电子衍射实验,该实验是荣获诺贝尔奖的重大近代物理实验之一。

下图所示的是该实验装置的简化图。

下列说法不正确的是( )A.亮条纹是电子到达概率大的地方B.该实验说明物质波理论是正确的C.该实验说明了光子具有波动性D.该实验说明实物粒子具有波动性,实物粒子也具有波动性,亮条纹是电子到达概率大的地方,不能说明光子具有波动性,故选C。

3.质量为m的粒子原来的速度为v,现将粒子的速度增大为2v,则该粒子的物质波的波长将(粒子的质量保持不变)( )A.保持不变B.变为原来波长的两倍C.变为原来波长的一半D.变为原来波长的√2倍,粒子速度为v时,λ1=hmv;粒子速度为2v时,λ2=h2mv ,λ2=12λ1。

可知C正确,A、B、D错误。

4.现代物理学认为,光和实物粒子都具有波粒二象性。

下列事实中突出体现波动性的是( )A.一定频率的光照射到锌板上,光的强度越大,单位时间内锌板上发射的光电子就越多B.质量为10-3 kg、速度为10-2 m/s的小球,其德布罗意波长约为10-28 m,不过我们能清晰地观测到小球运动的轨迹C.人们常利用热中子研究晶体的结构,因为热中子的德布罗意波长与晶体中原子间距大致相同D.以上说法均不能体现波动性,能清晰观察到轨迹,说明宏观物体的粒子性。

利用热中子研究晶体的结构正体现了实物粒子的波动性。

5.已知氢原子基态能量为-13.6 eV,电子质量m=9.1×10-31kg,电子的动能E p,求氢原子中基态电子的德布罗意波的波长。

A(2021·湖北等八省联盟联考)Later this month,Tate Britain will host its first Van Gogh exhibition since 1947.Here we’ve rounded up 4 of his best paintings before the show.Potato EatersPotato Eaters was Van Gogh’s first major work and,despite a distinct lack of colour,it was one that he was most proud of.His aim was to represent the difficulties of country life,so the farmers are painted in earthy tones with rough faces and bony hands.He was more concerned with conveying his message than achieving technical perfection in this painting.IrisesVan Gogh finished almost 142 pieces during his stay in the Saint Remy de Provence asylum(精神病院),where he was a voluntary patient from 1889 to 1890.This piece was started shortly after he arrived there.The hospital garden provided much inspiration for the artist during his stay there.Originally,the flowers in this work were painted purple but the red pigment(色素) faded over time and has now turned blue.Cafe Terrace at NightDespite being painted more than 130 years ago,this cafe still exists in France and has since been renamed the Cafe Van Gogh.This artwork marks the first time Van Gogh’s famous post-impressionistic star-filled sky was seen in a piece,and it was painted on the ground,in person,rather than from memory.While the artwork doesn’t bear his signature,it’s widely known to be Van Gogh’s,as he mentioned Cafe Terrace at Night in a number of his letters.Wheat Field With CypressesThis piece was inspired by the view from Van Gogh’s asylum window and was finished on the spot.The work was the title of three paintings that offer an insight into his stay at the hospital.Van Gogh was so pleased with the summer landscape that he made threecopies there,one of the same size—which hangs in the National Gallery,and two smaller copies which he planned to gift to his mother and sister.1.Which painting did Vincent van Gogh take most pride in?A.Irises.B.Potato Eaters.C.Cafe Terrace at Night.D.Wheat Field With Cypresses.2.What is the original color of the flowers in Irises?A.Purple.B.Blue.C.Red.D.Yellow.3.What do the last two paintings have in common?A.They were the same in size.B.They had more than one copy.C.They were signed by the artist.D.They were painted on the ground.B(2021·山东临沂期中)Haley Curfman,25,of Blackwell,Oklahoma,is a teacher at Blackwell Public School and last year she bought a plain(朴素的) white dress,which she set up a station in her classroom for her students to decorate,encouraging them to go and draw on the dress whenever they had free time.Haley set up a station at a table with the dress and some colored markers so that her students could draw on it,having first seen the idea on Pinterest.After the kids had finished the design,she then surprised them all by wearing the dress to class,sharing pictures of herself in it on Meta in a post that has since been shared over200,000 times.For teachers looking to do something similar for their own students,Haley said that she bought the dress off Amazon for less than $20 about six months ago and pre-washed the dress before she started the project.She used markers from Walmart.But she said these things can be bought in other places.She said,“To do the project,I set up a station at a table with the dress and markers.It takes about two weeks to a month to complete as we just work on it here and there when time allows.You’d better give the students enough time so that they don’t have to hurry.”“Teachers have been sharing their dresses,T-shirts,etc.with me that they’ve been creating since the 1950s with the same idea.It is amazing,and I love the fact that you are sharing them with me!Thank you all so much for your kindness and support,” she wrote on Meta.Asked why she came up with the idea,Haley told Scary Mommy,“We don’t have art in our school,so I always try to do little creative projects when possible.”4.What did Haley use the plain white dress to do?A.To teach her students painting.B.To prepare for her presentation.C.To ask her students to draw on it.D.To help her students with their homework.5.What do we know about the finished dress?A.It took Haley by surprise.B.It is kept by Haley at home.C.It is the product of a new idea.D.It has enjoyed popularity online.6.What should a teacher do if he or she wants to follow Haley’s example?A.Buy the same dress online.B.Give the kids enough time.C.Buy the same markers in Walmart.D.Leave the finished work untouched.7.Why did Haley carry out the project?A.To teach art to her students.B.To show her idea on Pinterest.C.To share it with other teachers.D.To excite her students’ creativity.C(2020·河南高二期末)The Museum of Old and New Art(MONA) in Tasmania,Australia,isn’t the only museum to have shut its gates because of the COVID-19 pandemic,but it stands out because of its unique,human artwork.As hard as it is to believe,Tim is both a man and an artwork. A former tattoo parlor(文身) owner from Zurich,in Switzerland,he agreed to have his back tattooed by artist Belgian Wim Delvoye in 2006,and has been exhibiting his body art in museums and art galleries ever since. He has been coming to MONA since 2011,for work that can last up to six months at a time and see him sitting with his legs crossed on a plinth,in complete silence,showing off Delvoye’s artwork.And even though MONA closed down on March 18,he continues to sit in the empty museum for six hours a day.That is his job...Tim learned about Wim Delvoye’s plan to create a human artwork from his girlfriend,and immediately said that he would be up for it.After meeting with the artist,he satthrough 40 hours of tattooing over two years.A few years ago,the art on his back—an artistic tattoo of the Madonna with a skull above her head—was sold to German curator(馆长) and collector Rik Reinking for $162,500.For six hours a day,every day,Tim sits on his plinth,showing off his back tattoo.Even though there is no one there to admire it,he is also live streamed via the Internet,so who knows,maybe there is actually someone wanting to see his tattoo,or rather Delvoye.Tim never gives interviews;he doesn’t speak to anybody and doesn’t even show his face,if he can help it.He is just a canvas(画布) for an artist’s masterpiece.“It’s not the Tim show,” Tim said in a video for MONA.“I’m just decoration in the Wim show.”8.What made MONA in Tasmania,Australia unique in the world?A.Allowing Tim to work as an artwork.B.The special human artwork made on Tim’s back.C.Being closed during the COVID-19 pandemic.D.An artistic tattoo made by Wim Delvoye.9.What does the underlined sentence in paragraph 2 mean?A.Tim is working hard to be an artwork.B.Tim is a hard-working man in MONA.C.That Tim is an artwork is unbelievable.D.Tim is a man who has many artworks.10.How long did Tim work as an artwork?A.14 years.B.9 years.C.20 years.D.6 hours.11.What does Tim think of himself?A.A great man artist in Australia.B.A successful businessman.C.Delvoye’s works’ decoration.D.A tattoo parlor owner.D(2021·广东中山高二期末)Paintings and sculptures can be a feast for the eyes of visitors to art museums,but today their viewing is also an unconventional treatment for people with mental illness.Last month,a group of Canadian doctors started to write a new kind of prescription(处方),which gives patients free access to the Montreal Museum of FineArts(MMFA).There,they will have a “relaxing,revitalizing experience” looking at the museum’s collections,according to MMFA.Nathalie Bondil,the museum’s director general,believes that being in contact with culture and arts can help with wellbeing.“In the 21st century,culture will be what physical activity was for health in the 20th century,” she said.Each prescription will allow not only the patients but also their family or friends to go with them.In the museum,the visitor can appreciate the artworks,and take part in a wide range of activities including drawing,sewing and making a sculpture with recycled materials.The new treatment is said to be the first of its kind in the world.But there’s increasing evidence that the display of visual art,especially art depicting(描绘) nature,can have positive effects on people with depression,anxiety and self-esteem problems.In 2017,the UK’s All Party Parliamentary Group on Arts,Health andWellbeing(APPGAHW) also released a report stating that “the time has come to recognise the powerful contribution the arts can make to our health and wellbeing”.Is it possible for art to improve overall health?We may not know the answer yet.But one thing is certain,more and more people today are persuaded by the idea that “art is a good medicine”.12.What prescription did the group of Canadian doctors give to mental patients?A.Get conventional treatment.B.Relax by experiencing nature.C.Join in some physical activities.D.Appreciate paintings and sculptures.13.What might Nathalie agree with?A.Contacting culture and arts can make people rich.B.Visiting art museums can help keep people healthy.C.Culture will replace physical activities in the 21st century.D.Mental patients should go to museums with their family.14.What do we know about the new treatment?A.It can help with mental problems.B.Nothing has proved it right so far.C.It was used before by visual artists.D.APPGAHW doubted its value.15.What is the best title for the passage?A.Will MMFA be open to patients?B.Is there a new treatment for artists?C.Will fine arts improve mental health?D.Is there a better medicine than art?第二节(共5小题;每小题2.5分,满分12.5分)根据下面短文,从短文后的选项中选出能填入空白处的最佳选项。
